Yet another promising request wrapper.
Promise-based, using the excellent
bluebird by
defaultPromise.catch(). This ensures
that all errors are handled, and often cleans up the code by clearly
separating out error handling. The HTTPError instance has all the
properties of a normal response.npm install preq
var preq = require('preq');
return preq.get({ // or preq.request({ method: 'get', .. })
uri: 'http://google.com/',
headers: {
'x-foo': 'bar'
},
query: {
q: 'foo'
},
// body for POSTs or PUTs, can be object (serialized to JSON), Buffer or String
})
.then(function(res) {
/**
* {
* status: 200,
* headers: {
* date: 'Sat, 21 Feb 2015 01:47:40 GMT' // , ...
* },
* body: '<!doctype html>...</html>' // or object if json
* }
*/
})
.catch(function(err) {
// Any response with HTTP status >= 400
// err is HTTPError with same properties as response above
});
preq-specific parameters / methodspreq passes through most options directly to
request, so see its documentation for
advanced options.
Additionally, it defines or modifies these request options:
method: Lowercase HTTP verbs. Automatically set by the verb methods (preq.get(),
.post() etc).uri: use uri, not url.query: query string parametersbody: String, Buffer or Object. If an object is supplied, the
serialization depends on the content-type header. Supported:
application/json.*multipart/form-dataapplication/x-www-form-urlencodedretries: Maximum number of retries. Exponential back-off is used between retries.timeout: Total request timeout.The connection timeout, maximum time to establish a TCP connection to the host is 5 seconds by default
and can be altered with PREQ_CONNECT_TIMEOUT environment variable.
Also see the tests for usage examples.
